Formulation and properties of a newly developed powder geopolymer grouting material
Highlights The powder geopolymer grouting material (S-F powder Geopolymer) is developed. The formula of this newly developed material is confirmed. The physical and mechanical properties are evaluated.
Abstract This paper aims to develop a new kind of powder geopolymer grouting material (S-F powder Geopolymer) and investigate the properties. The slag powder, fly ash, alkali activators A and B, chemical additive, reinforcing material and water were employed to prepare this material. The single factor and orthogonal tests were conducted to study the composition of S-F powder Geopolymer. The physical and mechanical properties were evaluated by a series of laboratory tests such as fluidity, bleeding and expansion rate, mechanical properties tests et al. The results show that the optimum formula of S-F powder Geopolymer is that slag powder to fly ash is 80:20, the alkali activators A and B are 8% and 6.5%, the reinforcing material is 9% and the water reducing agent is 1%. In addition, the S-F powder Geopolymer has good physical and mechanical properties, which can ensure the performance of road repaired by this material. The S-F powder Geopolymer can be used to fill void beneath cement pavement slab and to repair crack of cement-stabilized base of asphalt pavement. The results of this paper will help the practice to have better understanding on the powder geopolymer grouting material and give recommendations to guide future field application of this material.
